I am following the code in the Developing Applications with PI AF SDK - Online Course.
As you can see I am trying to populate the UOMs of the selected attributes from the top window to the drop down list. I am basicly copying the code in the course video, but it failed to populate the drop down list. I am just wondering if the code is still valid.
The code related to this function is attached below. I have also attached the whole project files in the zip file.
